UNITED STATES PATENT C r THOMAS BARBOUR, OF BELFAST, IRELAND.

HACKLING MACHINE.

Application filed June 3, 1926, Serial No. 113,521, and in Great BritainJune 16, 1925.

This invention relates to machines for hackling flax, hemp, jute andanalogous fibres. In machines of this class as usually 1 constructed itis customary to grip the material to be hackled between suitable holderswhich are caused to rise and fall between revolving sheets to which areattached pins or combs which hackle or comb the material during itsupward and downward movement. In this arrangement it is obvious thatowing to the material rising and falling while the pins of the revolvingsheets pass through it, various portions of the same holder full ofmaterial are subjected to different forms of treatment according to thespeed the pins pass through the material, the said speed varying as theholders rise or fall or remain stationary. With a view to overcomingthis objection it has been proposed to vary the speeds of the hacklesheets during the upward and downward movements or the holders by asomewhat complicated arrangement of change gearing and cam actuatedclutch mechanism.

According to this invention the rise and fall of the head, or gearingeffecting same is utilized to control a diiferential motion whereby therevolving sheets are driven at such varying speeds that the speed atwhich the pins pass through the material remains constant or practicallyconstant whether the material is rising, falling, or remaining in astationary condition.

In the accompanying drawings Figure 1 is an elevation of the lower partof a hackling machine provided with a differential motion in accordancewith the present invention.

Fig. 2 is a horizontal section of the mechanism shown in Fig. 1. y

F 3 is a side elevation in diagram showing the improvement in itsgeneral environment.

A indicates a lever which is raised and lowered by a cam on andconnected by a rod a and chain or other flexible connection with apulley l on a shaft 2 on which is fixed another pulley 3 to which isattached a flexible element 4 from one end of which is suspended therising and falling head 5 carrying the flax holders 6, and from theother end of the flexible element 4 is suspended a weight 7, all ofwhich parts operate in the well known manner. The lever A is mountedupon a shaft a and rigidly connected with it is a toothed sector aGearing with the toothed sector a is a toothed wheel a which is rigidlyfixed upon a sleeve forming part of a toothed wheel a The latter gearswith a wheel a which in turn geai's with a wheel a" of the differentialmotion and rotates it in alternate directions to add speed to thehackling sheets 9 when the channel is falling and subtract speed whenthe channel is rising. lhe wheel a carries two bevel wheels a which gearwith two bevel wheels a at opposite sides of the wheels a One of thewheels a is rigidly fixed to the shaft B which lrives the hackle sheetsand the other wheel is rotatably mounted on such shaft and carries awheel 6 which is driven by a change wheel Z2 and bevel gearing b fromthe main driving shaft C.

lVhat I claim as my invention and desire to secure by Letters Patent inthe United States is 1. In a hackling machine, mechanism forreciprocating the material and actuating hackling means to operate onthe material, and including a differential motion device so controlledby the movement of said material and driving the hackling means as toproduce a uniform hackling action without regard to the direction ofmovement of the material.

2. In a hackling machine, mechanism for reciprocating the material andactuating hackling means to operate on the material, and including adifi'erential motion device controlled by the movement of said materialand operable to drive the hackling means at substantially the same speedrelatively to the material in the variations of movement of saidmaterial.

3. In a hackling machine, a reciprocatory head, hackling means tooperate on the material movable with said head, and mechanism forreciprocating said head and actuating said hackling means and includinga difierential motion device so controlled by the movement of said headand driving the hackling means as to produce a uniform hackling actionwithout regard to the direction of movement of the material.
